+# zcartesianProduct
+
+> Compute the Cartesian product for two one-dimensional double-precision complex floating-point ndarrays.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var zcartesianProduct = require( '@stdlib/blas/ext/base/ndarray/zcartesian-product' );
+```
+
+#### zcartesianProduct( arrays )
+
+Computes the Cartesian product for two one-dimensional double-precision complex floating-point ndarrays.
+
+```javascript
+var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
+var zeros = require( '@stdlib/ndarray/zeros' );
+
+var x = new Complex128Vector( [ 1.0, 2.0, 3.0, 4.0 ] );
+var y = new Complex128Vector( [ 5.0, 6.0, 7.0, 8.0 ] );
+var out = zeros( [ 4, 2 ], {
+ 'dtype': 'complex128'
+});
+
+var v = zcartesianProduct( [ x, y, out ] );
+// returns [ [ [ 1.0, 2.0 ], [ 5.0, 6.0 ] ], [ [ 1.0, 2.0 ], [ 7.0, 8.0 ] ], [ [ 3.0, 4.0 ], [ 5.0, 6.0 ] ], [ [ 3.0, 4.0 ], [ 7.0, 8.0 ] ] ]
+
+var bool = ( v === out );
+// returns true
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a one-dimensional input ndarray.
+ - a two-dimensional output ndarray.
+
+
+
+
+
+
+
+## Notes
+
+- Pairs are stored as rows in the output matrix, where the first column contains the first element of each pair and the second column contains the second element.
+- For input arrays `x` of length `M` and `y` of length `N`, the output array should have shape `[M*N, 2]`, where `M*N` is the number of rows and `2` is the number of columns.
+- If `M <= 0` or `N <= 0`, the function returns the output ndarray unchanged.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
+var zeros = require( '@stdlib/ndarray/zeros' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var zcartesianProduct = require( '@stdlib/blas/ext/base/ndarray/zcartesian-product' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+
+var x = new Complex128Vector( discreteUniform( 6, -50, 50, opts ) );
+console.log( ndarray2array( x ) );
+
+var y = new Complex128Vector( discreteUniform( 4, -50, 50, opts ) );
+console.log( ndarray2array( y ) );
+
+var out = zeros( [ 6, 2 ], {
+ 'dtype': 'complex128'
+});
+
+var v = zcartesianProduct( [ x, y, out ] );
+console.log( ndarray2array( v ) );
